To all whom t may concern:

Be it known that I, ALBERTV STUFFLEBEAM, l citizen of the United States, residing aty Paris, in the county ofLoganan'd State of Arkansas,'have invented certain-new vand useful Improvements f in Shaft Couplings,`

of which the following is a specification. l

" This invention relates to churns, and. more particularly jto that vclass that are provided with,` twodashers capable ofy rotation-in opposite directions.

1 A Thev object of this-invention is 4to provide Y amount of power.

an'improved means for a churn of the kind above described .for rotating the dashers of*A the saineA at agreat speed with the minimum f Another object of Ythis rinvention is the production ofia churn having dashers ca.-

pable of rot-ation in opposite directions and means. intermediate the dashers and operate ing means for the same, to facilitate thedisconnection fof the dashers andthe operating means. Y r :l A still further object of this 'invention is to provide an improved .operating shaft for the dashers that will accomplish the purposes set. forth above.

. A still further object of this inventionfis` the production of a device of the kind above described that is simple in construction, efficient in operation and consists of the minimum number of parts.

With these and other objects in View, this invention consists of certain novel constructions, combinations and arrangement of parts as will be hereinafter fully described and claimed. l

In the accompanying drawings -4 Figure 1 is-a view in elevation of the improved churn with a portion of the milk or cream receptacle broken away to show the dashers positioned within the same.

Fig. 2. is a view in elevation of the improved operating shaft used with this invention with a part of the same shown in vertical section.

Fig. 3 is a sectiontaken on the line 3-3 of Fig. 1.

.Referring to the parts by reference numerals, 10 denotes the base of the churn having an upwardly extending standard 11 at one end thereof and webs 12 formed integrally with said base and said standard to provide a substantial structure.V Atl the opposite'end of the standard 11 from that of the formation of the webs 12 are spaced ,speciation q1; Letters raient.

arms 13.

Y, vlounted kfor'rotation-within the milk orV cream receptacle 19 is a shaft 20, having. the

dasher 21 secured to the sameby means-of f thefset screw 22 passing ,through the hubl of the dasher and engagingxthe said shaft.I This shaft 20 iszmade of two portions, an` upper and a lower one, the lower onehaving 2 an enlarged head 23 at the up er endr thereof provided with a socket 241,said'socket being square in cross section.Y The upper .part of l ing 16 formedr intermediate its length. C Formed in the standard 11 in alinement with' the shaft 20 ccunp'iises`an. elongated eii-. .l

larged portion:v 25 adjacentthe upper f yend y thereof, and at the lower end of thesame is a projection 26 that is square 'in cross section and adapted -forplacement in the'fsocket l 24: formed in the enlarged head 23 of the lower portion yof the shaft 20.

A sleeve 27 is also mounted for rotation in the receptacle 19, and has mounted on the lower end thereof a dasher 28 secured to the same by means of the set screw 29. This sleeve 27, as will be seen, is positioned over the lower portion of the shaft 20, and the upper end of the sleeve abuts against the shoulder formed on the shaft 20 by means v of the enlarged head 23,v and.v positioned upon the upper portion ofthe shaft 20 between the substantially elongated enlarged portion 25 and the upper edge ofthe enlarged head 23 of the lower portion of the shaft 20 is a sleeve 3 0. Said sleeve 30 and sleeve 27 are connected by means of the col.- lar 31 having thereduced ends 32 through which thefset ,screws 33 passto engage the sleeves 30 and 27 and thereby securing them rigidlytogether. l

Mounted on the sleeve 30 and spaced from the upper edge of the collar 31 by means of the washer 34, is a beveled gear 35. A beveled gear 36 is also keyed to the upper end vof the shaft 20. A third beveled gear 37 is set forth.

pinion 39 that meshes with a gear 40 that is secured to a stub shaft 41 that is positioned in the bearing 18 and secured thereto by a eotter pin 42. A handle 43 is secured to `one end of the stub shaft l1, and by rotating the same gives movement to the gear-40 thence to the pinion '39 and by means of the beveled gears 35, 36 and 37 to the shaft 20 and the sleeves 27 and 30 which, of course, having the dashers keyed thereto, rotate the same. n

It will be seen that a device has been constructed that will accomplish the objects as The collar 31 and the set screws 33 incombination with the sleeves 27 and 30 and the shaft 2O afford a detaohing means, whereby the dashers 21 and 28 can be easily detached from the operating `means and the receptacle 19 can be moved to a desired position and' the dashers withdrawn from the same.

It will also be seen that the operatingmeans for the s ame is avery substantial. structure, inasmuch as there is providedenlarged bearings 16, 17 and 18 vfor the shaft 3S and stub sha-ft 41. The .enlarged bearings `14: at the end of the spaced arms -13 afford a substan-` tial supporting-means forthe sleeve 30 and the sha-ft 20. ,l n
